Answer:
don't ask for an explanation. your answer is below.
Step-by-step explanation:

Using cosine rule, the length of the required side = sqrt(32^2 + 35^2 - 2 x 32 x 35cos 120)
= sqrt(1024 + 1225 - (-1120))
= sqrt(2249 + 1120)
= sqrt(3369)
= 58.04
Answer:
x=15
Step-by-step explanation:
5x+(180-9x)+(180-8x)=180
total of a triangle angles is 180
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Isolate the variable y

Divide by -2 both sides

The solution of the inequality is the shaded area below the dashed line 
To plot the inequality find the intercepts
The y-intercept is the point (0,3) (value of y when the value of x is equal to zero)
The x-intercept is the point (-12,0) (value of x when the value of y is equal to zero)
Plot the intercepts
Drawn the dashed line
shaded the region below the dashed line
